As CMMC 2.0 rolls out piece by piece, DoD contractors need to know the latest to stay ahead. This blog breaks down the most recent CMMC 2.0 updates, what they mean for your business, and how you can prepare for upcoming certification requirements. Whether you’re already deep into compliance efforts or just getting started, now is the time to ensure your cybersecurity strategy aligns with the DoD’s latest expectations.
The Department of Defense (DoD) published the final rule for 32 CFR in the Federal Register on October 15, 2024, and the rule became effective on December 16, 2024. This rule establishes the CMMC 2.0 program, creates the CMMC marketplace, and establishes protocols for certification. However, 48 CFR, which implements CMMC requirements in federal contracts, hasn’t yet been finalized. However, it’s likely that DoD contracts will begin including CMMC requirements starting in Q2 of 2025, with full implementation by 2028.
Understanding the timeline for the implementation of CMMC 2.0 is crucial for ensuring your business remains eligible to bid on DoD contracts. Here's an overview of the phased rollout process along with some key milestones.
The DoD has adopted a phased approach to implement CMMC 2.0, allowing contractors time to achieve compliance:
Phase 1 begins with the effective date of the CMMC Title 48 rule, anticipated in early to mid-2025. During this phase, Level 1 and 2 self-assessment requirements will be included in applicable solicitations and contracts as a condition of award.
Phase 2 starts one calendar year after Phase 1. Level 2 third-party assessments conducted by Certified Third-Party Assessment Organizations (C3PAOs) become a condition for contract awards.
Phase 3 initiates one calendar year after Phase 2 begins, involving government-led Level 3 assessments for contracts handling the most sensitive Controlled Unclassified Information (CUI).
Phase 4 arrives one year after Phase 3, marking full implementation with CMMC requirements included in all applicable DoD solicitations and contracts, including option periods.
December 16, 2024: The CMMC Final Rule (CFR 32) became effective.
January 2, 2025: CMMC assessments commenced.
Early to Mid-2025: Anticipated effective date of the CMMC Title 48 rule, marking the beginning of Phase 1.
Mid-2025: CMMC requirements expected to start appearing in new DoD contracts.
2028: Target date for full implementation, with all DoD contracts including CMMC requirements.
It should be noted that prime contractors can flow down these requirements to their supply chain well in advance of the government roll out.
The final publication of CMMC 2.0 in December, 2024 marked a big milestone in a long process. CMMC 2.0 was first introduced in November 2021 to streamline and simplify the original CMMC 1.0 framework proposed about a year and a half prior at the start of 2020.
If you’re familiar with CMMC 1.0, you might recall the significant complexity and challenges it posed for many small to mid-sized defense contractors. The DoD introduced CMMC 2.0 to simplify the process while still ensuring strong cybersecurity standards. Let’s break down the key differences and how they impact you.
One of the most notable changes in CMMC 2.0 is the shift from a five-tiered model to a simplified three-tiered model, making compliance more accessible and more easily understood.
While CMMC 1.0’s five level approach was thorough, it often proved overwhelming for small and mid-sized contractors, particularly those unfamiliar with advanced cybersecurity practices. With CMMC 2.0, the DoD has streamlined the framework by reducing the number of compliance levels from to the following three:
Another significant update in CMMC 2.0 is the removal of the 20 unique practices that were part of the original CMMC 1.0 framework. In CMMC 1.0, these practices were introduced as additional requirements beyond established cybersecurity standards like NIST SP 800-171. While they aimed to enhance security, they often caused confusion and increased the complexity of compliance for contractors.
With CMMC 2.0, the DoD has eliminated these unique practices, fully aligning the framework with existing, well-recognized standards derived from NIST SP 800-171 and NIST 800-172. This simplifies compliance and eliminates redundancy. For contractors, this means you can focus on adhering to established, well-documented standards without worrying about additional, unique requirements and more easily integrate CMMC compliance into your existing cybersecurity efforts. If you’re already implementing NIST SP 800-171 controls, you’re well on your way to meeting the requirements of CMMC 2.0.
CMMC 2.0 introduces a major change in how assessments are conducted. Under CMMC 1.0, every contractor, regardless of the level they were pursuing, was required to undergo a third-party assessment conducted by a C3PAO. While thorough, this approach would have been time-consuming and costly, especially for smaller businesses.
CMMC 2.0 takes a more flexible approach, tailoring assessment requirements based on the level of compliance. Level 1 requires an annual self-assessment and annual affirmation. For the majority of companies at Level 2, a C3PAO assessment is required every three years, though select programs may only require a self-assessment every three years. In both cases, affirmation is required annually. For the relatively small number of contractors aiming for Level 3 certification, a DIBAC assessment is required every three years along with an annual affirmation.
By introducing self-assessment options at Levels 1 and 2, CMMC 2.0 reduces costs and administrative burdens for contractors who don’t handle highly sensitive data. At the same time, the use of third-party and government-led assessments at higher levels ensures that robust security measures are verified where they’re most needed.
One of the most contractor-friendly updates in CMMC 2.0 is the introduction of Plans of Action and Milestones (POA&Ms). Under CMMC 1.0, full compliance was required at the time of certification. This meant that even minor deficiencies could prevent you from achieving certification, often leading to significant delays and additional costs.
CMMC 2.0 offers a more practical approach. With the allowance of POA&Ms, your organization can achieve conditional certification while addressing minor gaps over time. POA&Ms let you document specific areas where your organization falls short and outline actionable steps and timelines for addressing them. This reduces the immediate financial and operational burden for small and mid-sized contractors, letting you focus on the most critical aspects of cybersecurity before addressing minor deficiencies.
However, it’s important to note that POA&Ms aren’t a free pass. The DoD will set strict parameters around their use, including:
CMMC 2.0 introduces a new waiver process, giving contractors greater flexibility in meeting compliance requirements under certain conditions. In CMMC 1.0, no waiver process existed, meaning that contractors had to fully comply with all requirements, regardless of whether specific circumstances justified an exception. This rigid approach would have created challenges for businesses working within tight deadlines or unique operational constraints.
Under CMMC 2.0, the introduction of waivers allows companies to address specific challenges in their contract while maintaining their eligibility for DoD contracts. Here’s what you need to know about this change:
This new process benefits contractors by better balancing flexibility with accountability. If you’re working on a non-prioritized contract and face challenges meeting a specific requirement within a tight timeline, a waiver could allow you to proceed with the understanding that the requirement will be addressed in the future. This process helps contractors navigate real-world challenges while ensuring that cybersecurity remains a top priority.

The changes introduced in CMMC 2.0 have significant implications extending beyond just the prime contractors to the entire DoD supply chain. If your business handles FCI or CUI at any level, understanding and complying with these requirements is essential. Prime contractors must ensure their own compliance and verify that their subcontractors meet the necessary requirements. Subcontractors are equally accountable for meeting CMMC requirements, as their work often involves handling FCI or CUI shared by their primes.
Failing to meet CMMC 2.0 requirements by the specified deadlines can have serious consequences for your business, including:
To avoid these pitfalls, it's imperative to begin preparing for CMMC 2.0 compliance immediately. Assess your current cybersecurity posture, identify gaps, and develop a plan to meet the necessary requirements ahead of the deadlines. Early action will position your business for continued success within the defense contracting landscape.
Despite CMMC 2.0’s simplified process, achieving CMMC compliance is still a complicated and time-consuming process. Here’s a checklist for how to get started with your CMMC journey:

CMMC will not replace NIST 800-171. Instead, CMMC 2.0 is designed to work in alignment with NIST standards, particularly NIST SP 800-171 and SP 800-172. CMMC acts as a framework to ensure that contractors implement and maintain the cybersecurity controls outlined in these standards.
There is only one overarching CMMC framework, but there are two rules that implement it:
CMMC 2.0 defines three levels of compliance, each tailored to the sensitivity of the information being protected. Level 1 focuses on basic cybersecurity practices, requiring 17 controls derived from NIST SP 800-53 to safeguard FCI. Level 2 applies to contractors handling CUI and requires implementation of all 110 controls from NIST SP 800-171. Level 3 is for the most sensitive contracts involving critical CUI and builds upon Level 2 by incorporating additional advanced controls from NIST SP 800-172.
The CMMC 2.0 level you should pursue depends on the type of information your organization handles and the requirements outlined in your contracts. It’s expected, however, that the majority of DoD contractors seeking CMMC compliance will likely be aiming to meet Level 2 requirements.
